Abstract :
Based on the system of optical code-division-multiple-access (OCDMA), the optimization of optical orthogonal codes (OOC) (49, 3, 1, 1) is selected, the split-step fast Fourier transformed (SSFFT) method is used to analyse the transmission performance of picsecond OCDMA systems and the decoding output at different rates. The results show that the third-order dispersion (TOD) at 100 Gb/s user data rate generates distortion to the optical pulse shape with an unsymmetrical structure at the front or back edge, but correlation decoding of OCDMA inhibit the effect of TOD to some extent. The results also show that influence of TOD was more serious at 200 Gb/s user data rate, and the method of dispersion compensation can highly inhibit the influence of TOD.
